17th Edition of TOP500 List of World’s Fastest Supercomputers Released

MANNHEIM, ; KNOXVILLE, TENN.; & BERKELEY, CALIF. – In what has become a much-anticipated event in the world of high-performance , the 17th edition of the “TOP500” list of the world’s fastest supercomputers was released today (June 21). The latest edition of the twice-yearly ranking finds IBM as the leader in the field, with 40 percent in terms of installed systems and 43 percent in terms of total performance of all the installed systems. In second place in terms of installed systems is with 16 percent, while Inc. retained second place in terms of performance (13 percent). SGI Inc. was third both with respect to systems with 63 (12.6 percent) and performance (10.2 percent). The list is compiled by Hans Meuer of the University of Mannheim, Erich Strohmaier and Horst Simon of the U.S. Department of Energy’s National Energy Research Scientific Computing Center, and of the . The list was released and analyzed at the 2001 Conference in Heidelberg. At the top of the list, the U.S. Department of Energy’s Accelerated Strategic Computing Initiative (ASCI), which had claimed the top four slots on the previous TOP500 list, is now joined by the Department of Energy’s National Energy Research Scientific Computing Center (NERSC), an unclassified supercomputing center at Lawrence Berkeley National Laboratory (LBNL) in Berkeley, Calif. The IBM ASCI White system at Lawrence Livermore National Laboratory is still the number one supercomputer in the world, with an improved performance of 7.2 teraflop/s (trillions of calculations per second) on the Linpack . The number two spot is now taken by the new IBM SP system at NERSC/LBNL. At number five is a new Hitachi SR8000/MPP at the University of Tokyo. The list now indicates 12 systems exceeding the 1 teraflop/s level using the Linpack benchmark. The number eight system is an NEC SX5 at Osaka University and is the first classical vector system to break the 1 teraflop/s (Tflop/s) barrier. The TOP500 already contains 25 systems exceeding 1 teraflop/s level for peak performance. Two of these systems are IBM Netfinity clusters at NCSA and Shell, at numbers 30 and 31 respectively. The list exhibits unbroken growth at all ranges of performance. The total combined performance of all 500 on the list is 108.8 Tflop/s, compared to 88.1 Tflop/s six month ago. Increased performance also resulted in 132 systems which had made the previous list failing to make the latest edition. The “slowest” system on the newest listing is 67.8 gigaflop/s, compared to 55.1 Gflop/s 6 months ago and 43.82 Gflop/s in June 2000. The new TOP500 list, as well as the former lists, can be found on the Web at http://www.top500.org/. According to the compilers of the list, the following trends can be seen: * The retained its prime position as supercomputer user and producer, with only small changes in geographical distribution. * The number of machines used in industry decreased slightly to 236 from 245. * The number of machines used in research stayed stable at 118 (down from 119). * The number of machines used in academia continues to rise to 92 from 86. * All vector-based systems are of Japanese origin.

# # # All changes are from November 2000 to June 2001:

Highlights from the Top 10:

- ASCI White is #1 with an increased performance of 7.2 TF/s on the Linpack - Two new systems broke into the leading group of four ASCI systems from last year. - #2 is a new IBM SP system at NERSC/LBNL - #5 is a new Hitachi SR8000/MPP system at the University of Tokyo - Two more systems are new in the TOP10: - #8 a NEC SX5 installead at Osaka University, the first vector based system in the TOP500 - #10 a new IBM system at NCEP, which is an identical sister system to #9 at the same location - 12 systems have Linpack performance above 1 TFlop/s - 25 systems have peak performance above 1 TFlop/s including two IBM Netfinity clusters (#30 and #31) - 1.18 Tflop/s is the entry point for the Top 10

General highlights from the Top 500: - 132 systems fell of the end of the TOP500 since last June - Total accumulated performance is 108.8 TFlop/s compared to 88.1 TFlop/s 6 month ago - Entry level is now 67.8 GF/s compared to 55.1 GF/s 6 month ago - The entry point for the top100 moved from 181 GF/s to 241 GF/s.

Trends over time: - The US keeps it's prime position as supercomputer user and producer with only little changes in geographical distribution - The number of machines used in industry decreased slightly to 236 from 245. - The number of machines used in research stayed stable at 118 (from 119). - The number of machines used in academic continues to recover to 92 from 86.

- IBM is dominating the TOP500. It is leading the list with respect to the number of systems installed and the installed performance with a stable share of 40% and 42%.

- Sun is second in the number of systems with 81 (16.2%) and fourth in performance with 8.6%.

- With respect to installed performance Cray Inc. keeps the second position with 13.1% of performance. (fourth in systems 9% (45))

- SGI is third with respect to systems with 63 systems (12.6%) (third in performance 10.2%)

- All vector based systems are of Japanes origin. TOP500 Sublist for June 2001 TOP500 Team http://www.top500.org/
